Hello,

New to the board, and new to D2s. I picked up a 2004 D2 with 111k recently and while checking things out I noticed that there is small bit of coolant flow coming into the overflow tank from the bottom right tube that connects underneath even when the engine is cool and hasn't been running for a while. At one point when it was cooled off, I opened the top lid and tried to see if there was air, however it appeared to just be coolant coming back through, seems to pick up in intensity slightly if the engine has been running a while, the coolant tank does not over flow or anything though. I'm just curious if this is normal?


Attached a video for reference. (not sure if its working actually)

Thanks,

Sounds like normal coolant flow from the TBH loop which flows into the coolant reservoir.
